THIRUVANANTHAPURAM: Kerala opposition leader Ramesh Chennithala has written a letter to CPM general secretary Sitaram Yechury asking the CPM leadership to reveal its stand on the allegations against the CPM-led state government.

According to Chennithala, the state government has blindly deviated from the principles advocated by the CPM. 'We have clear evidence which proves the involvement of the Chief Minister's office in the gold smuggling case. However, pinarayi Vijayan is behaving as if he has no clue about what is happening around him, ' Chennithala wrote.
